“Since, however, it had become clear to me that, technically speaking, the metaphysics of Descartes had largely been a clumsy overhauling of scholastic metaphysics, I decided to learn metaphysics from those who had really known it, namely, those very Schoolmen whom my own professors of philosophy felt the more free to despise as they had never read them. Their study has wholly convinced me, not at all that to philosophize consists in repeating what they have said, but rather that no philosophical progress will ever be possible unless we first learn to know what they knew.

The chaotic condition of contemporary philosophy, with the ensuing moral, social, political, and pedagogical chaos, is not due to any lack of philosophical insight among modern thinkers; it simply follows from the fact that we have lost our way because we have lost the knowledge of some fundamental principles which, since they are true, are the only ones on which, today as well as in Plato’s own day, any philosophical knowledge worthy of the name can possibly be established.

(…)

The great curse of modern philosophy is the almost universally prevailing rebellion against intellectual self-discipline. Where loose thinking obtains, truth cannot possibly be grasped, whence the conclusion naturally follows that there is no truth.”

“The modern secularist, or at least the educated modern secularist, needs to be brought up to the level of the ancient pagan before he is likely to take Christian revelation seriously. He needs a renewed understanding of the nature on which grace builds and apart from which faith, revelation, and the supernatural falsely seem to float in mid-air, without a foundation in reason or reality. He needs natural theology and natural law — natural theology and natural law grounded in the truths even the pagans knew, natural theology and natural law as articulated and defended within Scholasticism, within Thomism — and he needs it now more than ever.”
